Double Hung Windows

Double Hung Windows in Fort Lauderdale, FL | TruePane Windows & Doors

Double hung windows are the classic vertical-glide design Florida homeowners know from older coastal cottages and ranch homes, but the impact-rated versions we install are a different animal entirely. Both sashes open, both sashes tilt in for cleaning, and the whole assembly is built to hold its ground in a hurricane. If you’re replacing original windows in Rio Vista, Victoria Park, or Coral Ridge, this is the profile that keeps your home’s proportions intact while bringing it up to current Fort Lauderdale code. TruePane Windows & Doors installs impact double hungs across Broward County, and we’ve been doing it long enough to know which configurations work and which ones fight you.

Product Overview - Double Hung Windows

Double hung windows are the most recognizable window style in Fort Lauderdale’s older neighborhoods. Two sashes stack vertically, both can slide, and on our impact series both tilt inward so you can clean the exterior glass from inside your living room. That tilt-in feature matters more than people expect in a two-story home near Las Olas or along the Intracoastal, where exterior cleaning isn’t always simple.

What separates an impact double hung from a standard one is the glass package and the frame engineering behind it. Our impact double hungs carry laminated glass with a PVB interlayer, which means the glass is designed to stay in the frame even if something hits it hard. The frame options, aluminum or vinyl, are engineered to handle the wind loads and pressure cycling that come with being close to the Atlantic. This is not a coastal-cottage window with a tougher sticker on it; the whole system, glass, frame, balances, and hardware, is built to work together under load.

Architecturally, double hungs suit ranch homes, four-squares, and the Mediterranean-style houses you see throughout Fort Lauderdale. They give you ventilation control from either sash, which is genuinely useful in a climate where you open windows in January and close them in August. TruePane Windows & Doors installs this profile across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so we’re not tied to one manufacturer’s way of doing things. We select the line that fits your opening, your wind zone, and your budget, then install it level, plumb, and square.

Technical Specifications

Here’s what you’re working with on our impact double hung windows, in plain terms:

• Frame materials: Aluminum or vinyl. Aluminum is typically used for larger openings and commercial-adjacent work; vinyl is common in residential replacement scenarios where thermal performance matters more.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. You can combine Low-E coatings with the laminated impact interlayer for both impact protection and heat control.
• Finish options: White, almond, bronze, black, or tan. The bronze and black finishes are popular on modern and coastal-contemporary homes in Fort Lauderdale’s newer builds.
• Screen options: Half screen or full screen, depending on how you use the window and whether you want the look of a full screen frame.
• Sash operation: Both top and bottom sashes operate vertically and tilt inward for cleaning.
• Design pressure: Matched to your wind zone, up to +/-100, never higher. We do not oversell that number; your specific configuration determines what’s required.

Each window is quoted per opening. If you need a specific size, color, or glass package, we work through it on the estimate. Call (954) 280-4413 for a line-item quote.

Hurricane & Compliance Performance

Laminated Impact Glass
The glass in your double hung carries a polyvinyl butyral (PVB) interlayer laminated between two panes. Under impact, the glass may crack, but the interlayer holds the fragments together and keeps the window sealed. That’s the core of impact protection in Fort Lauderdale’s wind-borne debris zones, and it’s why we don’t install single-pane double hungs on coastal homes.

Miami-Dade NOA / Florida Product Approval
Each configuration carries a Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval number. These are issued per configuration, not as a blanket stamp for an entire product line, so we verify the specific approval on your quote before we order anything. Your permit submittal needs the right number, and we make sure you have it.

FBC / HVHZ Compliance
The windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Fort Lauderdale falls fully within HVHZ territory, which is the strictest wind and impact standard in the state. If a window isn’t designed for HVHZ conditions, it doesn’t belong on a Fort Lauderdale home. Plain as that.

TAS 201 / TAS 202 / TAS 203 Testing Context
These are the testing protocols HVHZ-rated products are run through. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. When we reference these numbers on a quote or a permit package, we’re telling you the window was tested to withstand the conditions Fort Lauderdale actually produces.

Design Pressure for Your Wind Zone
Design pressure, or DP, is the structural rating that says how much wind pressure the window can take. We match design pressure to your specific wind zone, up to +/-100, and never higher. Over-specifying a window past what your zone requires adds cost without adding real protection. We’d rather quote you the right window than the expensive one.

Energy Performance
Low-E and insulated glass options are available on these double hungs. If your east-facing windows in Fort Lauderdale get hammered by afternoon sun, a Low-E insulated package cuts heat gain without changing the look of the window. The laminated impact layer stays; the coating and airspace do the thermal work.

Color & Glass Options

You have five finish choices: white, almond, bronze, black, and tan. White still dominates in Fort Lauderdale’s older ranch and cottage stock because it matches existing trim and doesn’t fight the architecture. Almond and tan read warmer, which suits the Spanish-Mediterranean and Florida-style homes around Sailboat Bend and Shady Banks. Bronze and black are the choices for newer contemporary builds, especially with larger openings where the frame becomes a visual line rather than a trim detail.

On glass, think about what each room actually needs. Clear laminated impact glass is the baseline: full protection, no tint, maximum light. Tinted glass knocks down glare and solar heat, which helps on west-facing windows that get the brutal late-afternoon Fort Lauderdale sun. Low-E insulated glass is the efficiency play, cutting heat transfer while keeping the view clear. You can combine Low-E with tint if you want both, and many homeowners do on large glass facing open water. Our job is to help you pick the right package per room, not to upsell you into a glass menu you don’t need.

Installation by TruePane Windows & Doors in Fort Lauderdale

Here’s what our installation actually looks like when we put impact double hungs into a Fort Lauderdale home.

We start with a pre-install inspection of every opening. That means checking the condition of the rough opening, looking for water damage in the framing, and confirming the existing flashing and WRB are intact. In older Fort Lauderdale homes, especially those near the Intracoastal or in neighborhoods like Idlewyld where salt air has been working on the framing for years, that inspection often finds things the homeowner didn’t know about. We address them before the window goes in, not after.

Every window is set level, plumb, and square. That’s not a slogan; it’s the difference between a sash that glides smoothly and one that binds. We install per AAMA 2400/2410 practice, which covers installation of windows in exterior walls, and we use AAMA 812 low-expansion foam as the perimeter sealant. That foam seals the gap between the window frame and the rough opening without bowing the frame, which is a real failure point with sloppy installs.

We finish with a water test on the installed window, then cleanup that leaves your house the way we found it. On the permitting side, we’re familiar with HVHZ submittal requirements in Fort Lauderdale, and we help make sure the right NOA or Florida Product Approval documentation lands in your permit package. An impact double hung is only as good as its installation. The NOA rating assumes a correct install. If someone slaps it into the opening without proper anchorage and sealing, that rating means nothing. That’s why you hire someone who does this every week, not someone who does it between other jobs.
